Abstract
L'invention concerne un empilement de piles à combustible à membrane électrolytique polymère à haute température comprenant au moins deux piles à combustible à membrane électrolytique polymère à haute température (HT-FECF) et au moins un moyen de détermination de la concentration de CO2 du gaz cathodique. Ainsi, un procédé de contrôle de cet empilement de piles à combustible est possible et consiste à déterminer au moins la concentration CO2 du gaz cathodique. La concentration de CO2 de l'agent d'oxydation introduit peut également être déterminée. La concentration de CO2 est mesurée avantageusement dans la zone de piles individuelles, ou de segments de piles. Ceci peut être réalisé par exemple par une lance coulissante dans le canal du gaz cathodique ou encore par une pluralité de sorties (soupapes) dans le canal du gaz cathodique. En cas de dépassement d'une valeur seuil qui définit l'état normal de piles individuelles aptes au fonctionnement, des mesures correspondantes, telles que la déconnexion de tout l'emppilement et éventuellement le remplacement de piles ou de blocs de piles, peuvent être prises. Afin de fournir des informations plus précises, l'invention prévoit de déterminer la concentration de CO2 du gaz cathodique non seulement globalement, mais aussi à l'intérieur du collecteur à la sortie de piles individuelles ou de segments de piles.
